Application filed November 23, 1927. Serial No. 235,208.

My invention relates to water barriers, and more particularly to a formwhich 18 specially adapted for use in connection with metal casingwindows or other similar openings in concrete buildings. 7

The principal object ofmy inventionis to provide a simple and efiicientweather barrier which will prevent rain which may be blown in throughthe crevices between the window and its frame from passing interiorlyinto the building and down the walls and onto the floor. H

Another objectof my invention is to provide a water-tight, trough-likepool forming structure upon or in the sill of a window interiorly of anadjacent the window frame structure so that rain water seepingorcapillarially' creeping ,in through the window frame will accumulatein the trouglrlike structure and then be dischar ed automatically to theoutside of the building, against wind pressures. This latter featureisof particular importance, and is mainly due to the provision of apool-forming structure of suhicient volume ric capacity that the watertrapped therein, as herein described, creates suflicient head toovercome exterior wind pressure exerted against the small area of thedrain holes provided for the exterior discharge of water thusaccumulated.

Other objects of the invention are to im.-'

prove generally the efficiency of such devices and to provide a deviceor apparatus of this kind which is economical, durable and reliable inoperation, and economical to manufacture. I

Still other objects of the invention will appear as the descriptionproceeds, and while herein details of the invention are described andclaimed, the invention is not limited to these, since many and variouschanges may be made without departing from the scope of the invention asclaimed in the broader claims..-

In the accompanying drawing, which forms part of this specification, andin which like characters refer to like parts through out the severalviews; I

Fig. 1, is a perspective fragmentary view of a present day standard typeof construc tion of metal casing for windows especially adapted forconcrete buildings of factory or office type showin one form of waterbarrier associated with the window sill and frame;

Fig. 4:, is a sectional view along line H in Fig. 5 of a modified formofmy'devioe in which the water barrier is shown as part of the concretewindow sill and the discharge outlet passing through the sill; i I

Fig. 5 is a plan viewof the modified form of my device as shown in Fig.4.

In the construction which I have shown in Fig. 1, 2 and 3, awindowapertureis shown in a masonry wall 1, part ofwhich is seen in Fig.3. Asill 2, viewed from the interior of the building, as in Fig; 1,Supports thereon a metal window structure, shown infragmentary fashionin Fig. 1.

I do not limit myself to metal casings. The material might be wood oranotherv substance through which water may seep. The

window casing is usually, in the case of con crete buildings madefofrolled structural steel. The casing is divided at its centerby ainullion 3 of l iron. The mullion acts as a strut in the window opening.A pair of iron angled window frames having channel seats 5 to receivethe glass panes others- .in, are flanged as at 7, and are bolted bybolts 8 to the ,mullion 3 on the inside thereof. Altho I have shownthese particularstructural shapes 1 wish to make it clear that, I am notlimited to such. shapes. Neither am I limited to glass panes. The pane'sinight be made of other wellknown window materials. f i

.When a blowing rainstorm hits'the exterior of the mullions 3, as shownby the arrows in Figs. 1 and 2, the rain beats into rric.j;i

and through the crevices between the mullions 3 and the flanges, sinceit is not customary to introduce packing between the flanges andmullion. It is found that the water seeps throughthe entire length ofthe flange joint the wall 1 and finally uponthe floor.v Such water isasource of annoyance and often grea' damage .in factories andwarehouses. In Figs. 1, 2 and 3, I have shown one method of eradicatingthis heretofore uncorrected fault in this. commonly used structure.

A piece of flatstrip 1netal'9, Fig. 2, isbent as shown with two verticalgutters 10 on each end. The bent structure is slightly and flows ontothe sill '2 and then down springy and a little larger than the spacebetween the frames 4, so that the vertical gutters 10 are packed with awatertight material as rubber or tarred cord 11, Fig. 2, and sprung orwedged, as shown, intov position. The strip 9 is pressed to a seat withthe sill 2 as shown in Figs. 2 and 3, with a substance as tar or puttyto render same watertight at the sill contact line 12, thus forming abasin. Any storm water seeping into the pocket or trough 13 is thuseffectively dammed against flowing down the wall 1 and onto the floor.

' 'To speedily 'and automatically empty the basin of accumulated water,a pair of holes 14, Figs. 2 and 3, are drilled through the mullion 3,the approximate positions of these discharge apertures being indicatedby Figs. 1 and These apertures while they are small permit collectedwater to drain to the outside of the building, notwithstanding windpressure. There is a continuous and steady dripping away of the pool ofwater through the perture 14.

In Figs. 4 and 5 I have shown an alternative 1 form of construction.Instead of using a strip of metal to form a basin, I may make the troughor basin a part of the sill.

' As shown-in Fig.4, on an entirely new job a basin or trough 15 ismoulded into the sill 2. Instead of providing a discharge aperture inthe mullion 3, a passage 16 is run through the sill by inserting a pipeinto the sill in the manner shown in Fig. 4 before th'econcrete sets. Itis understood that the passage can be found in any other man ner. It isto be noted that the passage 16 is located 'a little to one side of thecenter, 5, in order to miss the strengthening rib of the mullion.

I Only two forms of characteristic, specific, pool forming structureswith external automatic discharge are herein disclosed. One is adaptedto be applied to buildings already erected, and the other is designed tobe applied to new buildings, in the course of construction. Variousmodifications of my herein disclosed devices maybe devised as associateseepage controls for doors, window and similar openings in buildings,without, avoiding my herein claimed improvement in the art.

As in the structure shown in Figs. 1, 2 and 3 the water collected intrough 15 drains oil through the building.

What I claim is:

j 1. A water barrier adapted to be used on passage 16 to the outside ofthe 'a window sill in conjunction with a window frame subject to rainseepage on the interior thereof comprising a plate adapted to be sprunginto operable position with respect to said'sill and frame providing atrough like chamber thereby, gutter means integral with said plate,means associated with --sa-id-gi1tter means adapted to retain said platein watertight condition in sprung position relative to said frame andsill, and means at the line of contact of said plate and sill to rendersaid trough likechamber watertight, means in said frame providing anoutlet discharge the exterior of the win dow for water accumulated insaid trough like chamber thru rain seepage.

2. A'water barrier adapted to be used with a window frame subject torain seepage and associated with a window sill comprising a plateadapted to be fixedly sprung against said frame whereby a troughlike-chamber is formed with the sill and frame, means providing awatertight contact between said sprung plate and said frame and sill,whereby rain water collected in said trough-like chamber will not flowby said barrier plate.

3. In a device as claimed in Claim 2, means associated with said frameproviding a discharge outlet for rain water accumulated in the troughlike chamber to the exterior of said window frame. f

4. A device of the class described adapted to be used in connection awindow frame and sill including a resilient member adapted to be sprunginto fixed position relative to said sill and frame to form atrough-like chamber and means associated with said resilient member andcooperatingwith said 1 sill and frame to render said member water tight.7 i 5. A window frame water barrier comprising a flexible plate, guttermembers associated with said plate at the ends thereof, and elasticmeans associated with said gutters, said plate cooperating with saidframe to form a trough-like chamber therewith said elastic means adaptedto render said plate watertight;
